We NEVER actually buy a pizza from anyone. It's so easy to make your own and you're totally in control of whatever ingredients you prefer. You can use your breadmaker's dough setting and make your own dough if you like - but we find frozen bases like those made by McCain to be perfect.
For the best quality pizza - don't add too much total topping, otherwise your pizza will end up soggy.
Best to check the cooking of your pizza about 1/2 way through the time; it will probably need to be turned since ovens can cook unevenly.
